Thus the wavelength of a 100 MHz electromagnetic (radio) wave is about: 3Ã10 8 m/s divided by 10 8 Hz = 3 metres. The wavelength of visible light ranges from deep red, roughly 700 nm, to violet, roughly 400 nm (for other examples, see electromagnetic spectrum).
Mumble, Putting a modem to bridge mode just makes it dumb, it will let anything pass though, though when hits the Router it will then get routed to where needs be. The option is really up to yourself. Once advantage would be, only the Router will need to be setup accordingly, as the modem just passes internet traffic.
Active Mode. Active mode is how FTP originally worked, and it is still supported (and occasionally required) by many servers. In active mode, the control connection is made from the FTP client but all data connections are made from the FTP server to the FTP client. (Yes, back the other way.) In order for this to work, you usually need either no firewalls or firewalls that understand the FTP protocol and can dynamically open ports between clients and servers that look like they are performing ACTIVE mode FTP transfers.
